Zambia integrated down-the-hole drilling rig fuel consumption [PDF]

6 FAQs about [Zambia integrated down-the-hole drilling rig fuel consumption]

How do you calculate the power consumed by a drilling rig?

(4) P p o = P a c + P 3 Where, P 3 is the power consumed by the friction between the core block and the bit. When the drilling rig is working, the axial feed of the drilling tool and the power consumed by the rotary motion can be calculated from the thrust, torque, and rotational speed.

How to reduce the energy burden of drilling and excavation?

To reduce the energy burden of drilling and improve the environmental performance of the mining process, the drilling and excavation of energy has to move towards the direction of sustainable development. Due to the complex and changeable stratum environment in the process of energy drilling and excavation, hard rocks are often encountered.

Why is the power of a drilling rig stable during idling and air-cutting?

Since the bit never contacts the rock during the idling and air-cutting process, the power of the drilling rig is basically stable at this time.

How does energy flow affect the working process of a drilling rig?

Thus, this research discusses the energy flow in the working process of the drilling rig, establishes the mechanism model of the EC in each stage of the drilling rig's working process, and combines the least squares support vector machine (LSSVM) model optimized by the improved whale algorithm to compensate the mechanism model data.

How to improve the accuracy of drilling rig EC prediction?

Given the problems existing in the mechanism model, to improve the accuracy of drilling rig EC prediction, different from the traditional pure mechanism modeling and data-driven modeling ideas, the data-driven model is used as an error compensator in parallel with the mechanism model, and the mechanism model is compensated and corrected.

How is data-driven compensation corrected in a drilling rig?

That is, the direction of the data-driven compensation is corrected by the error Δ E = E ˆ − E 0, and the training is completed when the ΔE is approximately close to zero, and the LSSVM data compensation model is obtained, thereby obtaining the output of the hybrid model during the working process of the drilling rig.
